As the name implies, successful execution of nagashi mangan rewards the player in the amount of a [[Scoring|mangan]] tsumo. The [[honba]] count increases the payment normally. If multiple players win with nagashi mangan, the different tsumo payments occur independently of each other.

* Some rules have nagashi mangan happen before players may reveal tenpai hands. The noten penalty is cancelled and noten riichis are not punished with [[chombo]]. Hand progression depends on whether East has won with nagashi mangan. This variant is used in the [[EMA rules]].
* Some rules score nagashi mangan like a win, before players reveal tenpai hands. [[Honba]] increase the payment, and the winner collects any riichi sticks on the table. The noten penalty is cancelled and noten riichis are not punished with [[chombo]]. Hand progression depends on whether East has won with nagashi mangan. This variant is used in the [[EMA rules]].
* Some rules have nagashi mangan happen at the same time as players reveal tenpai hands. The noten penalty is still cancelled, but hand progression depends on whether East is tenpai. This variant is chosen in the [[Tenhou rules|Tenhou.net rules]].
* Some rules merely score nagashi mangan like a bonus payment, not as a win. Nagashi mangan happens at the same time as players reveal tenpai hands. The noten penalty is cancelled and replaced by the nagashi mangan payment, but that payment is not affected by honba or riichi sticks. Chombo takes precedence over nagashi mangan payments. If there is no chombo, then hand progression depends on whether East is tenpai. This variant is chosen in the [[Tenhou rules|Tenhou.net rules]].
